In the three and six months ended June 30, 2012 and 2011, basic and diluted loss per share have been computed using only the weighted average number of common shares outstanding during the period without giving effect to any potential future issuances of common stock related to stock option programs, investor warrants or convertible notes, since their inclusion would be anti-dilutive.

For the three and six months ended June 30, 2012, 45,689,000 and 45,602,000 shares attributable to outstanding warrants, convertible notes and stock options, and for the three and six months ended June 30, 2011, 45,702,000 shares attributable to outstanding warrants, convertible notes and stock options were excluded from the calculation of diluted earnings per share because the effect would have been anti-dilutive.
